' AUTOMATIC STEELE-MACHINE.

Be it known t'hat I, ERAs'rUs E. VINKIIEY, residing at Lynn, in Massachusetts, have invented certain new and useful jlmprovenients in Automatic Sole-Machines; and I do hereby declare the following to be a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to controlling or corrooting mechanism which is adapted to correct the angular relation between the work and tool or between the work and feed mechanism, of machines in which the tool operates progressively along the work. The term too-l is used to designate any instrument or combination of instrumentalities for operating on the work. Machines of this character are extensively used in the-manufacture of boots andshoes for performing various operations upon the shoe soles or other parts connected or to be connected therewith. Many of these machines are provided with feeding means constructed to cause-a relative movement of the tool and workin. the general direction of the periphery of a shoe sole, and the prescribed travel of the tool along the work is secured by rela-' tively swinging the tool and work to correct their angular relation in accordance with the curvature of the sole, the relative swinging movements being usually effected by the operator, who swings or tips the work as the feed progresses to maintain the edge of the sole or'some marginal channel or abutment thereon in engagement with a suitable gage. The periphery of the sole or the marginal abutment with which the gage contacts constitutes a form or pattern for determining the pathof travel ofthe tool along the work.

It is one of the objects of the present invention to provide novel and improved mechanism for automatically correcting the angularrelation of the wo't and tool to maintain the tool in proper angularrelation to the edge or surface of the work or to the line of feed as its point of operation progresses along the work.

It is a further-object of the invention to provide mechanism for controlling the corrcctive swinging movements by the contour ofifi'ferm H which corresponds to the path of traveluifthe tool along the work.

Specification of Letters Patent.

Application filed April 2, 1906, Serial No. 3G9,4G1. Renewed November Patented Oct. 15,1912. 11, 1910. #Serial No.-51,796.

lVith these objects in view, one feature of the invention contemplates the provision in a machine provided with feeding means for effecting a relative travel of the tool along the work in the direction of the periphery of a form, which maybe a contour of the work, of mechanism controlled by the contour of the form for relatively swinging the feeding means and work to cause the path of travel of the tool along the work to correspond to the contour of the controlling form. Broadly considered, the form may be the peripheryor other contour of the article to be operated upon, or tern, and the relative feeding movement and the 'relative swinging movement may be caused'by movement of either the feeding means or of the form and work.

The broader features of the invention also contemplate the'use of any suitable mechanism for controlling the relative swinging or angular movements of the work and feeding means or of the work andtool by the contour of the form. It is preferred,'however, to control these movements by a feeler arranged to travel along a contour on the work and by its position to determine the corrective movements requisite for causing the path of travel of the tool along the work to conform to the outline of the contour, or for maintaining the tool in proper angular relation to the work.

The various features of the invent-ion will be readily understood from an inspection of the accompanying drawings and the followtrated therein.

In the drawings Figure 1 is a side elevation of an insole-channeling and slitting machine embodying the present invention. Fig. .2 is a vertical section through the work su port and the automatic guiding mechanism. Fig. 3 is a detail plan view, partly in section, showing the construction of the clutch; and Figs. 4, 5 and 6 are diagrammatic plans showing the manner in which the guide acts upon the sole blank.

In the drawings the invention is illus trated as embodied in a channeling machine of familiar form by the addition thereto of automatic mechanism for guiding the blank. T he channeling machine shown is, in its general construction. and mode of operation, the well-known Goodyear channeling machine 1 No. can-571,

such as is shown in the patent to Beckman,

and need not be particularly delng detailed description of the machine illusfed against the imives. The-machine is proscribed except in so far as .relatesto the automatic mechamsm- The machine pro- I vided with channeling and edge-slitting knives yieldingly mounted in a head, and with a rotating feed wheelancl a rotatihg work support by -which the work is held and vided alsowith anv edge gage to determine 2 the distance ofj the" cuts produced by the knives .from the edge of .the insole. The

' machine is alsorprovided with mechanism for automatically "swinging the blank to cor- "-rect its'position' with relation to the knives,

and to maintain its edge in theline of feed during the transfer of the point of operation of the knife about the sole. In the construction shown, this means comprises a guide roll 1 which is arranged to, engage the edge of the blank and is operated to properly swing the blankwhenever its edge tends to recede from the edge gage. Theroll is journaled on an arm 2 Wl'ilCll is pivotally mounted'concentrically with the axis of the rests,

work support 3- u'ponwh1ch the blank 4 and automatic mechanism is arranged to swing the guide rolllabout the axis of the work support-so aslto swing the blank.

1 The arm 2 is-supported I fixed to a; shaft8 which is journaled at its upper end in the bracket 9 on the frame of the machine on which the stud 6 is mounted,

' and" at its lower end in a bracket 10. The

member 1]. of the clutch comprises a disk journaled on the shaft 8 and connected by'a sleeve 12 with a bevel gear, 13. The 'gear 13 is connected by a gear 14, shaft 15,

-. and sprocket chain 16, with the driving shaft 1? by which the instrumentalities of the channeling machine are actuated. The work support 3 and feed wheel 18 are driven from I the shaft 17 in the usual manner. The outer and inner members 7 and 11 of the clutch -are connected and disconnected by means of a" ball 19 carried in a recess in the clutch memher 7. The recess has a wall 20 inclined to 11, so that under the influence of a spr ng plunger 21 the ball tends to pijfich between the clutch members and cause themto rotate together. The clutch is held normally out of operation however, by means'of a pin 22 havin a beveled upper end'which bears against the ball 19 opposite to the plunger 21. The pin 22 passes through a hole in the bottom of the clutch member 7 and is fi'xed in an arm on a sleeve 23 looselymounted concentrically with the shaft 8 and free to rise and fall. When the sleeve 23 and'pin 22 are raised the inclined of 'the pin thrusts the ball back out ofj-operativej,

the adjacent surface of the clutch memberengagement between theclutch members.

The sleeve 23 is provided with a flange 24 engaged by a lever 25pivoted-"on the frame of the machine. The lever 25 is connected by a link 26 with a bell-crank lever 27 pivoted on the frame of the machine. The lever '27 is formed at its upper extremity as a feeler 28 which engages the edge of the insole blank at one side of the edge gage 29. A spring 30 connected with the lever 27 tends to move the feelen forward and to raise the link 26 so as to permit-the pin 22 to fall and theball 19 to operatively connect the clutch memb.ers. A's pring 31 is connected with the lower end of the shaft 8 and with the frame of the machine, and

tends constantly to rotate the shaft 8 and arm 2 so as to press theguide roll 1 lightly against the edge of the sole blank. During the operation of the machine, so long as the work is properlypresented to, thevknives as lsfed, the feeler is; held back in the posi-. t1on of Fig. 4 by its engagement with the edge of the blank; but if at anytime, as, for

example, where ,a' sharp curvature is encountered in'the blank, the blank, owing to its curvatureat the point of operation, tends to recede from the edge gage, thefeeler moves forward under the influence of the spring 3.0"so as to remain in contact with the edge, and by this movement the clutch is thrown into operation and the guide is swung about the wonksupport until the sole blank has been swung into pro er position with relation-to the knives, this operation bein automatically discontinued as soon as the eeler is pushed. back-again by the edge oftheblank. The blank is automatically e'e'cted at the completion of the operation iihereon, and

the machine put into condition to receive a new blank, by automatic mechanism operating in connection with the guideg, .The'

shaft 8-is provided with a helical cam 32 inposition to be engaged by acamroll iafi on a lever 34 pivoted at 35 on thfraniel e fj the machine. A tension spring 36 tendsfcom, stantly to swing the lever 34 so as ind-(muse the cam roll 33 to engage and rotate the cam 32 and the parts connected therewith, Y but during the operation of the machine ona blank the lever 34 is held in the position of Fig. l by 'a detent 37 which engages the rear end of the lever. Thedetent is mounted on a rod 38- slidingly mounted in'bearin s on the frame of the machine and normal y held in the position shown by a stop collar 39 and a spring 40. During theoperation on a blank, after the' operation has proceeded aroundthe forepart and has been almost completed at the heel end of the shank the guide roll '1 syg'ngs clear ofthe heel. of the blank, as shown'ln dotted lines, Fig.. 6.

the pin 22 to strike the. forward end This movement causes the arm carblank.

ofthe sliderod38 and push the rod and the detent 37 back so as to releasethe lever 34. The lever is at once drawn down by the spring 36, and. the cam roll 33, acting on the cam'32, causes the guide roll to be swung back until it engages the outer edge of the blank, as shown in Fig. 6, whereby. the blank 1s swung so as to cause the knives to-crt. out

to the edge of the blank, and the continued movement of the guide roll then ejects the To prevent the clutch from interfering with this return movement of the guide roll and from acting while there is no work in the machine, the lever 25 is provided with :1 depending arm 41 engaging a cam surfacev 4-2 on the lever 3 The czim-roll'33 is normally a short distance below th'e'cam 32, and during the first movement of the lever 34 the cam 42, acting on the arm 41 swings the lever 25 sons to throw out the clutch and'hold it out regardless of the position of the feeler.

In order that the machine, after ejecting ablank, may be in position to receive another, automatic means are provided for raising the knives and thefeed wheel. The machine is provided with the usual means for raising these parts to insert the ork, including the usual hand lever 43, pivoted at at, but a pin 45 fixed in the hand lever is engaged byv a link 46 connected with the lever 34., The link is. slotted as shown-in dotted lines, so as to move freely over the pin 45 during the first movement of the lever 34, but during the last part of such movement after the blank has been swung away from the knives, the-link t6 actsto depress the hand lever and reuse the operating instrumentalities. The lever 34 is connected by a link 47 with. a treadle, (not shown) by which it maybe raised after a blank has been inserted to allow the operating instrumentalities to engage the work and to restore the lever 34 to the position of Fig. 1 so as to release the guiding mechanism.

@The operation in'general ofthe machine is "as follows :The operator "inserts a blank in the position of Fig. 4, the guide roll occupying the position shown in the figure, and then depresses'the treidle, permitting the lmives and feed wheel to engage the blank. The machine then operates automatical \y, swinging the blank attheangles between the shank and the forepart and at the tip of the toe by means ofthe auto I '11]Ltl(f= mechanism above described. After the cl anneling operation has proceeded en tirely hround thei forepart and to the heel parton the opposite side to that on which it is started}, the guide roll is automatically swung back tntil it encounters the outer edge of the blank as shown in Fig. 6, and by its pressure thereagainst it swings the blank so as to cause the knives to cut outward toby this operation.

. combination,

the edge and complete their operation the blank being discharged from the machine The machine is then ready to receive a new blank, the knives and feed wheel being raised.

By means of the" automatic guiding mechanism' above described the operator is re lieved from the necessity of attending to the' machine during the, course of its opera.- tion upon a blank, his services being required only in inserting a fresh blank, and therefore one operator may feed two or more machines. Sincethe work is guided automatically, the accuracy with which it is operated upon does not depend upon the care and skill of anoperator but is uniform.

Although the invent-ion has been described in connection/with a channeling machine of a particular form, it will be understood that it is applicable to machines of many kinds for operating" upon soles or insoles, and may be used, in addition. to machines of the character already referred to, machines for reinforclng insoles or in fact for performing any operation upon the marginal portion of .a sole orinsole in which 1t 15 necessary :to
